Description
Technical field
The utility model relates to Spray Saturator method technology field in the coking industry, particularly a kind of mother liquor heater.
Background technology
Adopting the Spray Saturator method to produce the sulphur ammonium is the common method that reclaims ammonia in the fine purification technique for coke oven gas flow process.Spray Saturator is that saturator and crystallizer are connected as a single entity, and it makes flow process more simplify.Adopt the mother liquor heater in this flow process, heat by heater from crystallization tank top part mother liquor, the saturator spray is returned in recirculation, so that saturator mother liquor temperature stabilization is in certain limit.Because it is ammonium sulfate liquor has stronger corrosivity, and is serious to equipment corrosion, therefore, very strict to the material requirement of mother liquor heater.
Present heater structure is the light pipe heat exchange structure, and heat exchange efficiency is low, therefore improve heater structure for the heat exchanger efficiency that improves heater to the chemical industry energy-saving and emission-reduction, increase the benefit extremely importantly, also meet the energy-saving and emission-reduction policy of China.
Summary of the invention
The purpose of this utility model provides a kind of mother liquor heater, improves the heater structure augmentation of heat transfer, improves heat exchange efficiency, guarantees the requirement of saturator mother liquor temperature stabilization.
For achieving the above object, the utility model adopts following technical scheme to realize:
A kind of mother liquor heater, comprise cylindrical shell, upper cover bobbin carriage, low head bobbin carriage, tube sheet, heat exchanger tube, deflection plate, pull bar and distance sink tube, described cylindrical shell is vertical structure, the upper cover bobbin carriage is provided with the mother liquor import, the low head bobbin carriage is provided with the mother liquor outlet, be respectively equipped with steam inlet, condensation-water drain, thermometric interface and pressure measurement interface on the cylindrical shell, top one side of cylindrical shell is provided with diffuses mouth, and described heat exchanger tube is spiral fluted tube or cross grooved pipe structure.
Described tube sheet is the stainless steel clad plate structure.
Corresponding mother liquor import department is provided with impingement baffle one on the described upper cover bobbin carriage.
Described steam inlet adopts the flaring joint pipe structure, and corresponding steam inlet place is provided with impingement baffle two.
Compared with prior art, the beneficial effects of the utility model are:
1) adopts spiral fluted tube or cross grooved pipe heat exchange, augmentation of heat transfer mainly is to be determined by the type of flow in the pipe in the pipe, when adopting the spiral fluted tube, it is mobile that the restriction that flows in the nearly wall of helicla flute place makes tube fluid do one-piece auger motion generation local secondary, the body resistance that helicla flute causes, produce reverse barometric gradient and make boundary layer separation, thus augmentation of heat transfer, and heat transfer property can improve 2 ~ 4 times than light pipe; When adopting cross grooved pipe, when tube fluid is flowed through transverse ring, form axial whirlpool near the tube wall, increased the disturbance in boundary layer, make boundary layer separation, be conducive to the transmission of heat, fluid passes through next transverse ring again when whirlpool will disappear, therefore constantly produce eddy current, kept stable augmentation of heat transfer effect.
2) tube sheet adopts stainless steel clad plate, can effectively prevent the corrosion of mother liquor, and mother liquor can be selected to enter from the upper end or enter from the lower end according to technological requirement, and technology changes flexibly.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, it is the example structure schematic diagram of a kind of mother liquor heater of the utility model, comprise cylindrical shell 8, upper cover bobbin carriage 3, low head bobbin carriage 17, tube sheet 4, heat exchanger tube 13, deflection plate 15, pull bar 14 and distance sink tube 12, cylindrical shell 8 is vertical structure, upper cover bobbin carriage 3 is provided with mother liquor import 1, low head bobbin carriage 17 is provided with mother liquor outlet 9, be respectively equipped with steam inlet 6 on the cylindrical shell 8, condensation-water drain 10, thermometric interface 7 and pressure measurement interface 11, thermometric interface and pressure measurement interface are used for placing sensor to measure shell vapor (steam) temperature and pressure, and cylindrical shell 8 tops are installed and diffused mouth 5.
The material of heat exchanger tube 13 and end socket bobbin carriage 3 adopts S39042, and the form of heat exchanger tube 13 adopts spiral fluted tube or cross grooved pipe.Because the mother liquor of its heating has severe corrosive, require equipment to have stronger antiseptic property, the material of the cylindrical shell 8 of mother liquor heater, deflection plate 15, pull bar 14 and distance sink tube 12 adopts S31603.Tube sheet is the stainless steel clad plate structure.
Corresponding mother liquor import 1 place is provided with impingement baffle 1 and prevents the direct impingement heat transfer pipe 13 of mother liquor and tube sheet 4 on the upper cover bobbin carriage 3.Steam inlet 6 adopts the flaring joint pipe structure, and corresponding steam inlet place is provided with impingement baffle 2 16.
During use, earlier the mother liquor heater mouth of pipe is connected, by diffusing air in mouthful 5 emptying shells, will diffuse mouthful 5 usefulness blind plates then and block, shell feeds steam and comes the interior mother liquor of heating tube layer, heat exchange tube structure as shown in Figures 2 and 3, when mother liquor stream is crossed spiral fluted tube and fluted tube, form local secondary at groove line place and flow and axial whirlpool, increased the disturbance in boundary layer, make boundary layer separation, thereby strengthened heat transfer.
The mother liquor of mother liquor heater can select mother liquor import 1 from the upper cover bobbin carriage 3 to enter or mother liquor outlet 9 from low head bobbin carriage 17 enters according to technological requirement, and when mother liquor was entered by mother liquor outlet 9, the function of mother liquor import 1 changed outlet into.
